BACKGROUND OF THE INVENTION

1. Technical Field

The present invention relates to an improved method, system and program for monitoring fitness activity in general and, in particular, to an improved method, system and program for managing fitness activity across diverse exercise machines with a portable computer system. Still more particularly, the present invention relates to a method, system and program for monitoring the real-time cumulative fitness activity of a user from fitness activity data received from a plurality of diverse exercise machines over a period of time at a single, portable computer system.

2. Description of the Prior Art

A fitness craze has recently swept the United States and other countries. From fat-free potato chips to treadmills, people around the world have become obsessed with weight loss and healthy living. Accordingly, record numbers of new fitness products/exercise equipment from multiple manufacturers have emerged to meet this obsession (including stair climbers, treadmills, recumbent bicycles, ski machines, rowing machines, weight lifting machines, and the like).

Many pieces of exercise equipment, when utilized regularly, are very useful for weight loss, for improving cardiovascular stamina, and for strengthening various muscles. Most exercise equipment includes a monitoring device that may include a pulse monitor, a distance meter, a rate monitor, a time monitor, a strain gauge, an accelerometer and/or any other sensor for measuring the physical activity/performance level of an user on the equipment. Moreover, monitoring devices typically request personal data from the user such as age, weight and desired physical fitness level. The monitoring device utilizes the personal data in combination with physical exertion and heart rate to estimate calories burned, fitness levels met, and other fitness related data. In addition, the monitor may adjust the resistance or speed of a piece of exercise equipment in order to aid the user in reaching and/or maintaining a fitness level for that exercise session.

One limiting factor of many exercise machines and monitors is that the user must reenter their personal data to the monitor each time the user utilizes an exercise machine. In addition, most exercise machines do not have a previous history of the user from which to provide data about improvement and to provide additional fitness goals. However, one solution to providing a history for a user is provided in U.S. Pat. No. 5,335,188 ('188). In '188, a speed and time elapsed of an exercise session on a bicycle is recorded. The user may choose to save the speed and time of an exercise session under an identifier for the user. The user may later select a particular exercise session as a standard of performance for subsequent performances whereby each subsequent performance is compared with the selected exercise session. However, while the bicycle monitor memory stores exercise sessions for a particular user at that bicycle, in a club or other venue where multiple bicycles are provided, the user may not always have access to the bicycle at which the session data is stored in order to add to the data.

Another limiting factor of many exercise machines is that they operate and monitor the user independent of one another. However, cross-training across multiple machines is popular in order to exercise different parts of the body. An individual may spend 20 minutes on a treadmill working a hills program where the monitor for the treadmill calculates a certain number of calories burned and other fitness related data. The individual may then move to a rowing machine that does not realize that the user has already worked for 20 minutes and thus calculates calories burned and other fitness related data as if the user only worked out on the rowing machine. An overall fitness level achieved by the user after working on both machines is not provided.

One solution to cross-training across multiple machines is provided in U.S. Pat. No. 5,598,849 ('849). In '849, an individual is provided with a user monitor that has a preferred exercise regimen of physical parameters such as heart rate stored therein. The user is required to monitor at least one physical parameter with the assistance of the user monitor and is preferably required during exercise to control his exercise to maintain the physical parameter as closely as possible to the preset values. After exercising is completed, the monitored physical parameters are proffered from the user monitor and sent to a master data processing system where the monitored parameters are stored and compared with the preset parameters in order to develop a fitness profile. However, a real-time fitness profile is not provided by the prior art. In addition, the exercise regimen is not alterable during the workout. Moreover, the user monitor is limited in that it operates independent of the exercise machine and therefore does not provide feedback to the exercise machine in order that resistance or another variable may be adjusted.

Moreover, another limiting factor of many exercise machines is that they are boring to utilize because of their inability to encourage a user to continue exercising. Display screens that depict a user's location within a selected exercise program may be provided; however, they typically include dull graphics. One solution to improving graphical rendering is provided in U.S. Pat. No. 5,947,868 ('868). In the '868 patent, an exercise monitor outputs a signal representative of the performance level of a user utilizing the exercise equipment (e.g. pulse rate, distance traveled, time exercised, rate of exercise, etc.). The performance level signal then is fed to a video game player wirelessly or via a cable.

The video game player preferably utilizes a hand-held video game player. To simulate the user, the output from the exercise monitor is utilized to control the video game character's performance level within a video game that runs on the video game player. For example, the lifetime of a video game character may be increased by peddling faster. However, while the video game player provides a graphical venue by which the user controls a video game character according to their fitness level, other types of graphical rendering, other than a video game are not provided. In addition, in order to utilize the video game player, a monitor that supplies a particular type of performance level signal must be coupled to the exercise machine. Another limiting factor of many exercise machines is that they do not provide a display that is adjustable dependent upon the user. For example, existing systems are limited in that they do not offer displaying output from an exercise machine in a particular language, dependent upon the user.

Therefore, in view of the aforementioned, it would be advantageous to provide a personal electronic exercise monitor that operates in real-time to transmit control signal to multiple diverse exercise machines to control the movement of the exercise machines, proffer fitness data from multiple diverse exercise machines, utilize the fitness data from each exercise machine to update cumulative fitness activity over a period of time, adjust the control signal to meet fitness goals and control a graphical rendering of current exertion and totals that are selected by the individual. In addition, it would be desirable to provide a personal electronic exercise monitor that transmits personal data and/or exercise program selections to an exercise machine monitor such that it is not necessary for a user to re-enter the data at multiple diverse exercise machines.

SUMMARY OF THE INVENTION

DESCRIPTION OF A PREFERRED EMBODIMENT

The present invention may be executed in a variety of systems, including a variety of computing systems and electronic devices under a number of different operating systems. In a preferred embodiment of the present invention, the computer system is a portable computing system such as a notebook computer, a palmtop computer, a personal digital assistant, a telephone or other electronic computing system that may also incorporate communications features that provides for telephony, enhanced telephony, messaging and information services. However, the computer system may also be, for example, a desktop computer, a network computer, a midrange computer or a mainframe computer. Preferably, in order to enable at least one of these communications features, the computer system is able to be connected to a network, such as the Internet by either a wired link or wireless link. In addition, the computer system may be a stand-alone system or part of a network such as a local-area network (LAN) or a wide-area network (WAN). Therefore, in general, the present invention is preferably executed in a computer system that performs computing tasks such as manipulating data in storage that is accessible to the computer system. In addition, the computer system includes at least one output device and at least one input device.

Referring now to the drawings and in particular to FIG. 1, there is depicted a block diagram of one embodiment of a computer system that may utilize the present invention. As depicted, data processing system 10 includes at least one processor 12, which is coupled to system bus 11. Each processor 12 is a general-purpose processor, such as IBM's PowerPC™ processor that, during normal operation, processes data under the control of operating system and application software stored in random access memory (RAM) 14 and Read Only Memory (ROM) 13. The operating system preferably provides a graphical user interface (GUI) to the user. Application software contains instructions that when executed on processor 12 carry out the operations depicted in the flowcharts of FIGS. 6, 7, 8, 9 and others described herein.

Processors 12 are coupled via system bus 11 and Peripheral Component Interconnect (PCI) host bridge 16 to PCI local bus 20. PCI host bridge 16 provides a low latency path through which processor 12 may directly access PCI devices mapped anywhere within bus memory and/or I/O address spaces. PCI host bridge 16 also provides a high bandwidth path for allowing PCI devices to directly access RAM 14.

PCI local bus 20 interconnects a number of devices for communication under the control of PCI controller 30. These devices include a Small Computer System Interface (SCSI) controller 18, which provides an interface to SCSI hard disk 19, and communications adapter(s) 15, which interface data processing system 10 to at least one data communication network 17 comprising wired and/or wireless network communications. In addition, an audio adapter 23 is attached to PCI local bus 20 for controlling audio output through speaker 24. A graphics adapter 21 is also attached to PCI local bus 20 for controlling visual output through display monitor 22. In alternate embodiments of the present invention, additional peripheral components may be added. For example, in alternate embodiments, a tactile display component may be provided.

PCI local bus 20 is further coupled to an Industry Standard Architecture (ISA) bus 25 by an expansion bus bridge 29. As shown, ISA bus 25 has an attached I/O (Input/Output) controller 34 that interfaces data processing system 10 to peripheral input devices such as a keyboard and mouse (not illustrated) and supports external communication via parallel, serial and universal serial bus (USB) ports 26, 27, and 28, respectively.

With reference now to FIG. 2, there is depicted one embodiment of a block diagram of a system for utilizing a personal electronic exercise monitor in accordance with the method, system and program of the present invention. As depicted, computer system 10 preferably acts as a personal electronic exercise monitor that accesses, interprets, and controls fitness data across diverse exercise machine platforms. A fitness profile 50, fitness goals 52, personal data 54, control programs 56, and electronic calendar 58 are preferably stored within a data storage medium 51 of computer system 10. While in the present embodiment data storage medium is depicted at internally accessible to computer system 10, in alternate embodiments, data storage medium 51 may be externally or remotely accessible to computer system 10. In addition, the data stored in data storage medium 51 is preferably updatable through downloads from other sources to computer system 10. Moreover, the data stored on computer system 10 is preferably efficiently stored in a particular data transmission format, such the extensible mark-up language (XML), or is easily convertible into the data transmission format.

Computer system 10 preferably communicates with multiple diverse exercise machines, such as exercise machine 38, via a bi-directional communications medium (or across a communication interface). In addition, as will be further described, computer system 10 may communicate with alternate server systems via a bi-directional communication medium. The communications medium may include wired or wireless communications or other communications media that enables bi-directional transmission of data. Moreover, the communications medium may include a link to a network, such as the Internet, or a direct data link.

In a wired embodiment of the communications medium, for example, exercise machine 38 is connected to computer system 10 via parallel, serial, or USB ports, or the communication adapter as depicted in FIG. 1. In a wireless embodiment of the communications medium, for example, exercise machine 38 is wirelessly connected to computer system 10 via infrared, radio frequency (RF), cellular and other wireless transmissions which are detected by computer system 10.

Data exchange across the communications medium is advantageously performed in at least one of multiple available data transmission protocols and is preferably supported by a common data structure format, such as the extensible mark-up language (XML) data structure format. Data transmission protocols may include, but are not limited to, Transmission Control Protocol (TCP), Internet Protocol (IP), Hypertext Transfer Protocol (HTTP), and Bluetooth. In addition, data may be transmitted in a secure manner via encryption or by technologies such as secure socket layer (SSL) or virtual private networks (VPN).

An example of an XML data file that might be transmitted from computer system 10 to exercise machine 38, as depicted below, preferably contains data that is distinguished by attributes on elements and may be wrappered within a larger element. For example, the data attributed to element “<TimeStamp></TimeStamp>” designates the time that the data was attributed to the XML data file. <TREADMILL TimeStamp=“888965153” MachineType=“Arc2000” UserID=“JANEXYZ” Speed=“30” Elevation=“5”>

In addition, in an alternate example, the XML data file might be formatted utilizing elements, as illustrated below. <TimeStamp>888965153</TimeStamp> <MachineType>Arc2000</MachineType> <UserID>JANEXYZ</UserID> <Speed>30</Speed> <Elevation>5</Elevation>

In the example, as will be further described, exercise machine 38 would receive the example XML data file and utilize the XML data file to control operation of exercise machine 38. The above described XML data file example is intended as a functional example of an XML data file that would control the speed and elevation of a treadmill. The elements, format of the elements and data included with the elements is provided to depict an example and is not intended to limit the types of elements, format of elements or data included with elements that are in an XML data file.

In the example of the XML data format as the common transmittable data format, a data validation file such as a document type definition (DTD) or schema is preferably utilized to validate XML data files. In addition, a schema preferably translates multiple XML data files. Moreover, a style sheet such as an extensible stylesheet language (XSL) file is preferably utilized to provide a style specification for the XML data at the receiving system. In particular, DTDs, schemas, and XSL files may be, for example, transmitted with an XML data file to a receiving system or downloaded at the receiving system from an alternate source. In the present example, the DTD or schema would verify that all the data required for transmittal to a particular exercise machine is included in the XML data file. For example, a speed and elevation may be required to validate the XML data file.

Exercise machine 38 advantageously transmits measurements in the common transmittable data structure format from real-time monitoring systems associated with exercise machine 38 including, but not limited to a pulse monitor, a distance meter, a rate monitor, a time monitor, a strain gauge, an accelerometer and/or any other sensor for measuring the physical activity/performance level of a user on a piece of equipment.

Detected exercise signals, such as a pulse, distance, rate, time, strain, etc, are preferably transmitted from exercise machine 38 in a common transmittable data format. For example, an example of an XML data file for a pulse monitor is described below where a user's pulse is measured between a particular time period at 80 beats per minute. In addition, an alternate form of XML formatting may be utilized. <TimeRange>888965153,888965160</TimeRange> <MachineID>45365</MachineID> <MachineType>PulseMonitor</MachineType> <Rate>80</Rate>

Computer system 10 is preferably enabled to compute current fitness activity based on the detected exercise in the form of a pulse, distance, rate, time, strain, acceleration, and any other sensed value that may be utilized to compute current fitness activity. In addition, in calculating current fitness activity, factors such as previously accumulated fitness activity stored in fitness profile 50, personal data 54, and the type of exercise machine are utilized to compute a realistic fitness assessment. Thereby, computer system 10 is enabled to compute and store cumulative real-time fitness activity within fitness profile 50 over a selected time period or session from across multiple diverse exercise machines.

Cumulative fitness activity over a selected time period is preferably computed from summing previously accumulated fitness activity for the selected time period with the current fitness activity. In summing the previously accumulated fitness activity and current fitness activity, computer system 10 may adjust the cumulative total to more closely reflect the fitness gained as a result of exercising on multiple machines over a period of time. For example, if a user exercises for an hour across three different exercise machines, the amount of calories burned by the user actually increases with prolonged exercise over a particular amount of time determined for that user and therefore is adjusted in the cumulative fitness activity.

In addition, to storing cumulative real-time fitness activity for a user over a particular period of time, individual sessions of fitness activity may also be recorded. For example, if a user exercises on a treadmill for 20 minutes and a rowing machine for 20 minutes, a cumulative fitness profile may be calculated and stored in fitness profile 50. In addition, fitness activity achieved from exercise on the treadmill and rowing machine may be stored as separate exercise sessions. Moreover, in addition to calculating cumulative fitness activity according to previously accumulated fitness activity, personal data 54 and the type of exercise machine, the types of food eaten by the user that day, fluid intake, medication usage and environmental exposure may be utilized to determine cumulative fitness activity data.

In particular, in addition to receiving detected exercise signals from exercise machine 38, detected exercise may be input by a user via input interface 66 or from another monitoring device. For example, a user may count the number of jumping jacks that they perform during a break between utilizing exercise machines. The number of jumping jacks can be entered into computer system 10 via an input interface 66 and computer system 10 computes fitness activity data for the jumping jacks and updates the cumulative real-time fitness activity data.

Input interface 66 may include, but is not limited to including, a keyboard, a mouse, a stylus, a vocal recognition system, a tactile-detectable device, a biometric detection device, a disk drive, a personal storage device adapter, and other devices which allow user input to computer system 10. Preferably, input interface 66 provides an interface with computer system 10 through which a user may supplement data provided by exercise machine 38. In addition, input interface 66 preferably provides an interface with computer system 10 through which a user may customize the functions performed by computer system 10 and data stored therein.

In addition, in an alternate embodiment, other monitoring systems may be associated with computer system 10. For example, a pulse monitor may be associated with computer system 10 that detects the pulse of a user as the user exercises on exercise machine 38, independent of exercise machine 38. In another example, a pulse rate monitor may record a pulse rate for a user over a period of time, such as during a foot race, and transmit the recorded exercise signals to computer system 10, independent of an exercise machine. Therefore, an exercise machine need not include monitoring systems for detecting health parameters during exercise. In addition, the cumulative fitness activity data calculated at computer system 10 may be supplemented with exercise measurements taken for exercise performed independent of exercise machine 38.

Personal data 54 stored at computer system 10 may include information that is relevant to determining fitness gains in a workout such as weight, height, age, percentage body fat, bone density, metabolism, health problems, prescriptions, diet, and other health related factors. For example, food and liquid intake for a user may be monitored by a portable computer system as described in U.S. patent application Ser. No. 09/466,000 and in U.S. patent application Ser. No. 09/560,386, both herein incorporated by reference. In another example, medication intake for a user may be monitored by a portable computer system as described in U.S. patent application Ser. No. 09/560,992, herein incorporated by reference. Moreover, environmental exposure of a user may be monitored by a portable computer system as described in U.S. patent application Ser. No. 09/560,163, herein incorporated by reference.

In addition, personal data 54 preferably includes a user's output preference for how cumulative fitness activity should be output. For example, a user may prefer a particular font size, colors, output device, graphical application, etc.

Moreover, in personal data 54, an individual can designate multiple levels of security for accessing fitness profile 50, fitness goals 52 and personal data 54 stored on computer system 10. For example, particular parts of personal data 54 such as age and bone density may be shielded from transmittal and access without a password. As will be understood by one with ordinary skill in the art, multiple types of security methods and filters may be applied to fitness goals 52, personal data 54 and other data stored on computer system 10.

Fitness goals 52 preferably includes data such as target heart rates, target caloric loss, target distance and speed, and other target fitness goals stored in a data storage structure. In addition, fitness goals 52 preferably includes selections of control programs from control programs 56 for particular exercise machines and selected exercise sessions. In particular, a control program may be preselected in fitness goals 52 for a particular exercise machine such that the control program is automatically selected if a user selects to utilize that particular exercise machine. In addition, parameters for the control program, such as a level of difficulty, may also be included in fitness goals 52.

An exercise session may include multiple selections of control programs from among control programs 56 for multiple machines that the user is intended to utilize over a particular period of time. The session of selections of control programs may be pre-selected by the user, determined by a trainer, or selected by computer system 10 dependent upon the goals of the user and other factors. For example, a session may be selected that includes a control program for a 20-minute interval on a rowing machine at a particular speed and thereafter a control program for a 15-minute interval on a step machine with a target heart rate. In another example, a user enters fitness goals and a selection of available exercise machines and programs on those exercise machines is selected by computer system 10 and provided to the user.

As mentioned previously, if a user or trainer does not select exercise sessions for an individual, computer system 10 may provide suitable exercise sessions that are selectable by the individual or a trainer. In particular, computer system 10 is preferably enabled to determine sessions based on an individual's personal data 54, exercise machines available to the user, and fitness goals 52 provided such as the type of event training for, the date of the event and other pertinent data. Alternatively, fitness goals 52 may include weight loss, cardiovascular strengthening, muscle strengthening, etc. Preferably, an individual can enter or download specific types of exercise machines that are available in a personal gym or health club, wherein computer system 10 determines suitable exercise sessions based on machine availability.

A control program selection or session of control program selections in fitness goals 52 may be added to an electronic calendar 58 on computer system 10 in order to schedule for the user what type of exercise should be performed each day and how much time should be allotted for exercise. This function is particularly helpful for people wanting to follow a particular work out schedule. For example, athletes training for an event, such as a triathlon, where a schedule is imperative to reach fitness goals and where multiple diverse exercise modes are performed consecutively, would benefit from an exercise program stored on electronic calendar 58. In addition, a trainer may prescribe a particular workout schedule for a client on electronic calendar 58.

Control programs 56 preferably includes multiple control programs for controlling each of multiple types of diverse exercise machines. For example, for a treadmill, one control program may provide for a flat race while another control program may provide for a hill workout. Each of control programs 56 preferably designate a particular type of work out session with goals for reaching particular speeds, heights, heart rates, etc. dependent upon personal data 54. In particular, control programs 56 are preferably downloadable onto computer system 10.

The parameters of control programs 56 are advantageously adjustable by the user such that the intensity of each control program may be varied. For example, a user may select to utilize a particular control program, such as a hill workout, for thirty minutes one day and for forty-five minutes another day. Computer system 10 is preferably enabled to adjust the hill workout control program for varying times, difficulties, etc.

When computer system 10 connects to exercise machine 38, computer system 10 preferably detects the type of exercise machine from a machine type signal transmitted from exercise machine 38 in the common transmittable data structure format. In response to detecting the type of exercise machine, computer system 10 checks whether a control program for the detected exercise machine is designated in fitness goals 52. If a control program is not preselected, then a selection of control programs available for controlling the machine are displayed to the user via output interface 68. In response to a pre-selection of a control program or a current designation of a control program, with parameter selections, a machine control signal is transmitted from computer system 10 to exercise machine 38 in order to control the functions of exercise machine 38.

As a user exercises, the detected exercise signals received from exercise machine 38 are preferably compared with the goals of the exercise program. For example, a heart rate of the user may be compared with a target heart rate for the control program in view of personal data 54 or a current cumulative fitness activity level in fitness profile 50. If a user is not reaching target goals, an indicator may be output to the user via output interface 68 and/or the machine control signal to exercise machine adjusted to facilitate the user reaching target goals. If the user is exceeding target goals, an indicator may be output to the user via output interface 68 and/or the machine control signal adjusted to reduce exercise intensity.

As another feature of computer system 10, a user may compete against other users via a communications medium with other computer systems that are monitoring real-time fitness activity data, where the fitness activity data is transmittable in the common data structure format. For example, alternate computer system 59 is monitoring real-time fitness activity data on exercise machine 61. In particular, multiple users may be utilizing the same type of exercise machine or diverse types of exercise machines where a single type of display profile or multiple types of display profiles show each of the user's paces compared with the other user's. For example, one user may be riding a stationary bicycle while another user is running on a treadmill. A graphically rendered game may be displayed to each of the user's at each of the user's computer systems that are monitoring their exercise. The game or other application preferably compensates for the differences in types of exercise to show one user's position compared to another user's position in the game. The users may be within an area local to one another, such as in a gym, or may be within a global area and are connected via a network connection.

As previously described, output preferences may be included with personal data 54 on computer system 10. The user-designated output preference may designate output preferences for a particular type of output interface 68 for a particular user. Output interface 68 may include, but is not limited to including, a graphical display, an electronic paper, an audio speaker, audio headphones, a tactile detectable device, or a printer. The output preferences may include, but are not limited to specifications such as the size, type and coloring of a font in a graphical display, the type of tactile-detectable output (e.g. Braille), the language or the metric amount displayed.

In addition, the output preferences may designate a particular game or other program that adds a pictorial representation of a fitness profile. For example, a game that displays the user riding through a jungle forest may be selected. Moreover, alternative output device may be coupled to exercise machine 38 that provide additional media. For example, a user may switch stations, volume and signal bearing media on controllers including, but not limited to, a radio receiver, a television signal receiver, a compact disk player or a tape player that is accessible from exercise machine 38. In addition, as will be understood by one with ordinary skill in the art, any form of visual, auditory or tactile media may be provided for the individual to detect their fitness profile.

Computer system 10 is advantageously a portable computer system, such as a digital telephone, a personal digital assistant, a laptop computer, or a palmtop computer that is easily transportable and compact. In addition, computer system 10 is advantageously utilized as a personal exercise monitor for monitoring exercise across multiple diverse exercise machine platforms and a temporary controller for controlling movement of multiple diverse exercise machine platforms when in use by a user associated with computer system 10. It is important to note that a user is able to customize the features available on computer system 10. Since the user advantageously supplies computer system 10, the user may select the type and quality of desired output. For example, the user may download games, audio and other programs from signal-bearing media into data storage medium 51. In addition, the user may utilize a computer system that includes a color display, or alternatively a black and white display. In addition, it is important to note that computer system 10 may be continuously upgraded without requiring the upgrade of machine monitor 40.

In addition, it is important to note that the exercise machine monitoring system of the present invention may provide for a gym setting in which a user's account included in personal data 54 is charged as the user exercises and the user provides computer system 10 in order to control each of multiple diverse exercise machines. For example, a user's account may be debited per machine usage, per type of machine utilized, per time on the machine, per number of calories burned or other criteria. Moreover, a user's account may be debited for downloading a particular game or upgrade.

With reference now to FIG. 3, there is depicted a second embodiment of a system for utilizing a personal electronic exercise monitor in accordance with the method, system and program of the present invention. As depicted, an exercise machine includes an at-machine exercise monitor 40 that includes a fitness calculator 46, predetermined exercise programs 44, and a machine controller 48 within a data storage medium 41 accessible to said monitor 40.

At-machine exercise monitor 40 preferably enables a user to control exercise machine 38 both independently of computer system 10 and dependent upon computer system 10. Input interface 76 provides an interface for a user to enter personal data and select a predetermined exercise program from among predetermined exercise programs 44. Fitness calculator 46 calculates current fitness activity based on personal data and detected exercise signals. Machine controller 48 transmits a control signal to exercise machine 38 for controlling movement of exercise machine 38.

Alternatively, personal data may be transmitted from computer system 10 to at-machine exercise monitor 40. In addition, alternatively, a selection of a predetermined exercise program may be transmitted to at-machine exercise monitor 40. Moreover, alternatively, at-machine exercise monitor 40 acts as a “dumb terminal” receiving a control signal from computer system 10, such that exercise machine 38 is completely controlled by computer system 10.

Personal data transmitted from computer system 10 to at-machine exercise monitor 40 is preferably transmitted in an XML data file as shown below, where at-machine exercise monitor 40 is enabled to read the data file. In addition, a predetermined exercise program selection of program “5” for thirty minutes at exercise level “8” may be included in the data file. Moreover, an alternate form of XML formatting may be utilized. <TimeStamp>888965153</TimeStamp> <UserID>GeorgeG</UserID> <Age>30</Age> <Weight>180</Weight> <Program>5</Program> <ProgramTime>003000</ProgramTime> <ProgramLevel>8</ProgramLevel>

Referring now to FIG. 4, there is illustrated a block diagram of a machine usage system for a health club in accordance with the method, system and program of the present invention. Computer system 10 is preferably enabled to transmit a schedule request for particular exercise machines during a particular time period in the common transmittable data structure format via a network connection such as the Internet or a LAN connected to a health club server 80. For example, an XML data file including a request for a “Tread505” exercise machine on Feb. 23, 2000 from 1 PM to 1:30 PM is depicted below. In addition, an alternate form of XML formatting may be utilized. <TimeStamp>888965153</TimeStamp> <UserID>GeorgeG</UserID> <MachineRequest>Tread505</MachineRequest> <MachineRequestDay>02.23.2000</MachineRequestDay> <MachineReqTime>13:00:00,13:30:00</MachineReqTime>

Health club server 80 preferably includes a reservation database 81 containing a listing of each exercise machine available and any reservations made for the machines. In addition, time limits for each exercise machine may be specified. In addition, health club server 80 preferably includes user accounts 82 that may include a prepaid debit amount, a credit card number, bank account number, or other financial information that can be utilized to charge a user for a particular service.

The reservation server 80 compares the schedule requests from computer system 10 with available time slots in reservation database 81 and transmits a list of available scheduling to computer system 10. The individual may then select to reserve exercise machines from the available scheduling. In scheduling time, an identifier and/or password for the user is transmitted and stored with the reservation. In addition, the individual may select to be placed on a waiting list for exercise machines that are currently reserved during a requested time period. Computer system 10 is then notified if the time slot opens. Preferably, a session of scheduled exercise machines is added to an electronic calendar or other scheduling database on computer system 10.

In addition, reservation server 80 may be connected to multiple at-machine exercise machines 84 a-84 n via a communications medium. Exercise machines 84 a-84 n communicate with computer system 10 to receive a reservation identifier for the user and transmit verification requests to reservation server 80 to verify that a user has a reservation for an exercise monitor being requested by that user. In verifying a user, both the reservation stored in reservation database 81 and the account information for the user stored in user accounts 82 are verified. In addition, the user account may be debited. In receiving a verification, exercise machines 84 a-84 n are enabled to function for the verified user.

Reservation server 80 preferably tracks statistical data concerning the times utilized and frequency of reservation requests for exercise machines. By tracking reservation data, marketing and financial planning data can be collected. For example, peak hours for a health club can be determined. In addition, by tracking reservation data, a member might be limited in the number of times that they can schedule a reservation and later cancel the reservation. Either periodically or in real-time, data from each of exercise machines 84 a-84 n may be transmitted to reservation server 80 in order to track the usage of each exercise machine. In an alternate embodiment, data collected at each of exercise machines 84 a-84 n may be transmitted periodically or in real-time via a wireless transmission medium to a server or other data storage medium that compiles data about the usage of each exercise machines 84 a-84 n. Thus, whether an exercise machine is in use in a home gym or a health club, a manufacturer or owner can obtain data about the usage of the exercise machine via communications with each exercise machines 84 a-84 n.
